Let's start a serious discussion about how to solve the lack of numpy in IronPython. We could look into using ctypes (IronClad?) and wrap what already exists. We could look into a cross-platform DLL drop-in replacement. Between speed and compatibility, initially I'm most interested in compatibility. But speed should be a long term goal. We could write a pure-python prototype initially, and slowly move that to C#, or another CLR language. That would be useful for all non-C-based Python implementations, and would probably be quickest to write and test. A related note: Python3 just added a new matrix multiplication operator [1]. Hope to see more numpy-related functionality in standard Python in the future. Other ideas?
